Forex Valves manufactures and supplies Wafer Type Check Valves designed for reliable backflow prevention in industrial piping systems. These valves are engineered according to API 594 design standards and tested as per API 598 to ensure dependable performance, tight shut-off, and long service life across different process applications.
As an experienced Wafer Type Check Valve Manufacturer in India, we provide wafer check valves suitable for water treatment, chemical processing, power plants, HVAC systems, oil & gas, refineries, and other industrial pipeline applications. Our valves are available in different materials, pressure ratings, sizes, and seat configurations to meet specific project requirements.
A Wafer Type Check Valve is a compact non-return valve installed between pipeline flanges to prevent reverse flow of fluids. Unlike traditional flanged check valves, wafer designs offer a lightweight and space-saving solution while maintaining efficient flow control.
These valves automatically allow fluid flow in one direction and close when the flow reverses, protecting pumps, compressors, pipelines, and other equipment from damage caused by backflow.
Forex Valves manufactures wafer check valves with a wafer type end connection suitable for installation between compatible flanges. The compact construction reduces installation space, weight, and maintenance requirements compared to conventional valve designs.
Material selection plays an important role in valve performance, corrosion resistance, and operating life. Forex Valves offers wafer type check valves manufactured using industry-standard materials.
CS A-216 Gr. WCB is commonly selected for general industrial applications where strength, durability, and cost efficiency are required. Carbon steel wafer check valves are suitable for water, steam, oil, and various industrial fluid systems.
SS A-351 Gr. CF8M provides enhanced corrosion resistance and is preferred for aggressive chemical environments, marine applications, food processing, and pharmaceutical industries.
Different operating conditions require different sealing materials. Available seat options include:
The correct seat selection depends on fluid type, temperature, pressure, and operating conditions.
Forex Valves supplies Wafer Type Check Valves in multiple sizes and pressure classes to support different industrial requirements.
| Specification | Available Range |
